Moderate corn earworm migration risks are in the forecast on a nightly basis into early next week until a cold front passes through at least a portion of the corn-growing region. Southerly winds in between a cold front moving southeast in the northern corn-growing region and high pressure in the eastern corn-growing region and southern Appalachian Mountains may lead to scattered moth flights initially west of Lake Michigan for the next two nights, including portions of Nebraska, South Dakota, Minnesota, Iowa, Missouri, Wisconsin, and Illinois. By late in the weekend and early next week, the risk area nudges eastward just a little bit, it does appear that high pressure to the east may stay a little further west than anticipated but we could still see some scattered moth flights as far east as southwest lower Michigan into portions of northern Indiana early next week, with any migration risk in general staying west of I-75 or even slightly further west than that. Once the front moves southeast through the northern and central corn-growing region by later Tuesday into Wednesday, little if any migration risk will exist. Growers with crops at susceptible stages to corn earworm damage are encouraged to continue trapping and scouting efforts until the crop is no longer at risk.
